Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Antarctic Peninsula
The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San MartÃn in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctica. The Antarctic Peninsula is part of the larger peninsula of West Antarctica, protruding from a line between Cape Adams (Weddell Sea) and a point on the mainland south of the Eklund Islands. Beneath the ice sheet that covers it, the Antarctic Peninsula consists of a string of bedrock islands; these are separated by deep channels whose bottoms lie at depths considerably below current sea level. They are joined by a grounded ice sheet. Tierra del Fuego, the southernmost tip of South America, is about away across the Drake Passage. The Antarctic Peninsula is in area and 80% ice-covered. The marine ecosystem around the western continental shelf of the Antarctic Peninsula (WAP) has been subjected to rapid climate change. Over the past 50 ...

Airy Glacier
The Airy Glacier () is a glacier long and wide, flowing west to the northeast portion of Forster Ice Piedmont, near the west coast of the Antarctic Peninsula. The glacier was first roughly surveyed by British Graham Land Expedition of 1936–37, then photographed from the air by the Ronne Antarctic Research Expedition in 1947, and surveyed by Falkland Islands Dependencies Survey in 1958. It was named by United Kingdom Antarctic Place-Names Committee for George Biddell Airy, British Astronomer Royal, who in 1839 introduced a method of correcting magnetic compass A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with ...es for deviation.

Mount Timosthenes
Mount Timosthenes () is a prominent peak between the head of Hariot Glacier and the north side of Airy Glacier, 3 nautical miles (6 km) northwest of Peregrinus Peak, in central Antarctic Peninsula. Photographed from the air by United States Antarctic Service (USAS), September 28, 1940, and by Ronne Antarctic Research Expedition (RARE), November 27, 1947. Surveyed by Falkland Islands Dependencies Survey (FIDS) in December 1958. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) after Aristotle Timosthenes Timosthenes of Rhodes (Greek: ) ( fl. 270 BCE) was a Greek navigator, geographer and admiral in Ptolemaic navy.

Ronne Antarctic Research Expedition
The Ronne Antarctic Research Expedition (RARE) was an expedition from 1947–1948 which researched the area surrounding the head of the Weddell Sea in Antarctica. Background Finn Ronne led the RARE which was the final privately sponsored expedition from the United States and explored and mapped the last unknown coastline on earth and determined that the Weddell Sea and the Ross Sea were not connected. The expedition included Isaac Schlossbach, as second in command, who was to have Cape Schlossbach named after him. The expedition, based out of Stonington Island was the first to take women to over-winter. Ronne's wife, Edith Ronne was correspondent for the North American Newspaper Alliance for expedition and the chief pilot Darlington took his wife.

Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.

United Kingdom Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica.

Jean Rotz
Jean Rotz, also called Johne Rotz, was a 16th-century French artist-cartographer. He was born to a Scottish father and a French mother. Career Rotz was a member of the school of the Dieppe maps. He may have accompanied Jean Parmentier to Sumatra in 1529, and he definitely went to Brazil in 1539. His work was greatly influenced by these early French explorations, which induced him to create highly decorative maps. Failing to find employment with King Francois I, Rotz went to England in 1542 and entered the service of Henry VIII. He presented Henry with his manuscript atlas, the ''Boke of Idrography,'' which contained a two-hemisphere world map. This map showed the ''distraits of magallane'' (Strait of Magellan), the two Unfortunate Islands (''Insulas desfortunadas''), unnamed on the map, discovered during Ferdinand Magellan's voyage across the Pacific, and the strait between ''Lytel Java'' (Java Minor) and ''the Londe of Java'' (Java Major) through which the ''Victoria'', the last ...

King Henry VIII
Henry VIII (28 June 149128 January 1547) was King of England from 22 April 1509 until his death in 1547. Henry is best known for his six marriages, and for his efforts to have his first marriage (to Catherine of Aragon) annulled. His disagreement with Pope Clement VII about such an annulment led Henry to initiate the English Reformation, separating the Church of England from papal authority. He appointed himself Supreme Head of the Church of England and dissolved convents and monasteries, for which he was excommunicated by the pope. Henry is also known as "the father of the Royal Navy" as he invested heavily in the navy and increased its size from a few to more than 50 ships, and established the Navy Board. Domestically, Henry is known for his radical changes to the English Constitution, ushering in the theory of the divine right of kings in opposition to papal supremacy. He also greatly expanded royal power during his reign. He frequently used charges of treason and h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
